Ken Wilber's early writings on human development, as well as his more recent Integral model, have received significant attention in the field of transpersonal psychology as well as beyond. At the same time, the practical implications of Wilber's work for most fields, including transpersonal and mainstream psychotherapy, have largely gone unexamined. The goal of the dissertation was to bridge that gap in the field of psychotherapy. The first, dominant method of this dissertation was theoretical. A thorough evidentiary review of Wilber's Integral Model was conducted, along with an in-depth discussion of its relevance to psychotherapy, bolstering and modifying it with contributions from other eminent theorists and therapists. The second, supportive method involved the solicitation of real-life therapeutic case studies from practicing, Integrally-interested therapists. These clinical examples were used to substantiate this approach to psychotherapy as well as to draw upon the novel ideas and applications coming from within the burgeoning and diverse Integral movement. It was concluded that the Integral Model has immediate and practical applications within the realm of psychotherapy and shows significant support in the research literature. Further research is needed to establish its efficacy as well as to clarify how to best utilize its constructs within the context of psychotherapy..
